i wonder known if it is possible do this idea that i want to do.
i have a gate with motor and i want do :
at gate - a A esp8266 on AP mode and execute a ping to a ip fixed of other B esp8266 (this will be on car with station mode), so if B are nearly A will have ping so will open the gate else will close.
i dont known if its possible to put a relay on it.
thanks
